Further, constant pressure air feed opening 80 is communicated with constant pressure supply conduit 82.Constant pressure supply conduit 82 is communicated with constant pressure air supply pipe 54, and the carbon dioxide being adjusted to predetermined pressure by feeder 56 is supplied to the inner chamber of such as stomach 16 by constant pressure air feed opening 80 from constant pressure supply conduit 82.It should be noted in this article, this gas supply is called as the supply of constant pressure gas.
During observation inner chamber, when by piezometer 62 measurement gas pressure in feeder 56, the constant pressure gas supply performing inner chamber is all the time in predetermined pressure to keep inner chamber.
As mentioned above, in a first embodiment, by constant pressure supply conduit, the gas pressure measured in the constant pressure air supply pipe 54 be communicated with stomach 16 performs the pressure measxurement performed by piezometer 62, but, as described later, another conduit, such as, be specifically designed to the pressure measxurement that tonometric pressure measurement conduits may be used for being performed by piezometer 62.
Therefore, owing to directly not measuring the pressure in inner chamber, but by measuring the pressure in inner chamber with the conduit of inner space, therefore when constant pressure supply conduit 82 do not get clogged and constant pressure air feed opening 80 is opened in equal state, the accurate measurement of the pressure P 2 of inner chamber (in stomach 16) needs stomach 16 and constant pressure air supply pipe 54 to be interconnected.
But, high viscosity body fluid (Digestive system, blood etc.) is present in the inner chamber of people, and these body fluid adhere to far-end end face 44, thus completely or partially block the opening portion (constant pressure air feed opening 80) of constant pressure supply conduit 82, this probability causing the open state of constant pressure air feed opening 80 to change.Carry out measurement pressure when open state changes, accurate pressure measxurement can not be performed.Therefore, in the present invention, perform constant pressure described subsequently for pneumatic control, thus realize accurate pressure measxurement.
Fig. 3 shows the structure of execution constant pressure for the feeder 56 of pneumatic control.
As shown in Figure 3, feeder 56 comprise decompression part 84 and 86, be arranged on is connected with decompression part 84 in air feed feed pipe 52 switch valve 88a, be arranged on the control section 90 of part 84 and 86, switch valve 88a and 88b etc. that to reduce pressure with the switch valve 88b that is connected of part 86 and controlling of reducing pressure in constant pressure air supply pipe 54.
Decompression part 84 is supplied with high-pressure carbon dioxide gas by high-tension connector 56a from the high-pressure gas pipe 58 be connected with carbon dioxide cylindrical shell 60 with 86.Further, constant pressure air supply pipe 54 is provided with piezometer 62 and effusion meter 64, and this piezometer 62 and effusion meter 64 measure pressure and the flow of the gas gasifying, be depressurized to predetermined pressure by decompression part 86 and be supplied to constant pressure air supply pipe 54 from carbon dioxide cylindrical shell 60.The corresponding measurement result of piezometer 62 and effusion meter 64 is sent to control section 90.
Each in decompression part 84 and 86 is according to the predetermined pressure that to be reduced pressure to by the carbon dioxide supplied by high-tension connector 56a from the control signal of control section 90.Further, each in switch valve 88a and 88b opens or closes according to the control signal from control section 90.Control section 90 controls decompression part 86 and switch valve 88b according to the measurement result of piezometer 62 and effusion meter 64, thus performs constant pressure for pneumatic control.Unshowned piezometer can be connected with air feed feed pipe 52 with effusion meter in the accompanying drawings, thus detects supply gas pressure and air demand.
Constant pressure according to the present invention forced gas to be supplied to constant pressure supply conduit 82 for pneumatic control before the pressure measxurement be separated with the supply of above-mentioned constant pressure gas, thus removing bur, such as adhere to the liquid of constant pressure supply conduit 82 inside.This gas supply is called as flushing or catheters irrigation air feed.This flushing is substantially equal by measured pressure for making in the pressure in the inner chamber of such as stomach 16 and constant pressure air supply pipe 54, thus measures accurate chamber pressure.
Fig. 4 shows the first constant pressure for pneumatic control method.
Figure (chart) shown in Fig. 4 is the time diagram that the conduit of air feed and constant pressure air feed is rinsed in display, which show the flow of the time on horizontal axis and the supply of the constant pressure gas on vertical axis.
Here, flow be vaporized from carbon dioxide cylindrical shell 60, decompression part 86 be depressurized to predetermined pressure and be supplied to the flow of the constant pressure air feed gas (carbon dioxide) of constant pressure air supply pipe 54.
As shown in Figure 4, perform constant pressure air feed C1 with certain hour interval, and performed pressure measxurement before constant pressure air feed C1.Further, catheters irrigation air feed F1 must be performed before pressure measxurement.Particularly, in order to perform accurate pressure measxurement, preferably before by pressure measxurement, perform catheters irrigation air feed.Therefore, control section 90 not only sends and performs tonometric instruction, and instruction synchronously performs flushing by decompression part 86 and the flusher that forms of switch valve 88b and pressure measxurement, as shown in Figure 4.Now, control section 90 performs tonometric instruction not performing constant pressure air feed C1 and send during stopping gas supply, and sends the instruction performed for the gas being applied to flushing, thus performs flushing before pressure measxurement, as shown in Figure 4.
The first constant pressure at least equals the flow of the volume of constant pressure supply conduit 82 for this catheters irrigation air feed F1 supply in pneumatic control.Now, if mucus etc. adhere to the opening portion (inside of constant pressure air feed opening 80) of constant pressure supply conduit 82, then can perform catheters irrigation air feed F1 to increase the flowing velocity of air feed under the pressure higher than constant pressure air feed, thus blow away mucus etc.
Further, even if mode performs catheters irrigation air feed F1 with the flow being equal to or greater than the volume of constant pressure supply conduit 82 according to this, the volume of constant pressure supply conduit 82 is also much little than the volume of inner chamber, such as, when the volume of stomach is 1500cc, the volume of conduit is 15cc (in this example, the volume of conduit is 1/100 of the volume of inner chamber).Therefore, catheters irrigation air feed can not make the pressure of inner chamber sharply increase, thus applies tension force on object.
Here, the flow preferably supplied by catheters irrigation air feed F1 at least equals the volume of constant pressure supply conduit 82, and be only necessary the flow supplying the volume approximately corresponding to the conduit be made up of constant pressure air supply pipe 54 and constant pressure supply conduit 82, wherein constant pressure air feed gas is supplied to constant pressure air feed opening 80 from feeder 56 by the conduit that this is made up of constant pressure air supply pipe 54 and constant pressure supply conduit 82.
It should be noted, as shown by the dotted line in fig. 3, check-valves 54a can be arranged in the constant pressure air supply pipe 54 be communicated with constant pressure supply conduit 82, makes to be equal to or greater than at the flow of constant pressure air feed to perform catheters irrigation air feed from check-valves 54a to when the volume of the conduit of constant pressure air feed opening 80.
Therefore, due to before pressure measxurement (particularly, before by pressure measxurement) catheters irrigation air feed F1 removes and adheres to the liquid etc. of constant pressure supply conduit 82 inside, thus measured constant pressure air supply pipe 54 is communicated with mutually with its pressure by inner chamber completely, the pressure of constant pressure air supply pipe 54 is made to become the pressure being substantially equal to inner chamber, then perform pressure measxurement by piezometer 62, accurately can measure the pressure of inner chamber.
Fig. 5 shows the second constant pressure for pneumatic control method.
Fig. 5 is display the second constant pressure for the time diagram of the catheters irrigation air feed in pneumatic control and constant pressure air feed.
In addition, in the second constant pressure in pneumatic control, be similar to the first constant pressure air feed above-mentioned, perform constant pressure air feed C2 with certain hour interval, and performed pressure measxurement before each constant pressure air feed C2.Further, need before each pressure measxurement, perform catheters irrigation air feed F2.In addition, in this case, preferably before being about to carry out pressure measxurement, catheters irrigation air feed F2 is performed.
Perform the second constant pressure and continue the time period shorter than the catheters irrigation air feed F1 in the first constant pressure air feed for the catheters irrigation air feed F2 in pneumatic control, as shown in Figure 5, but there is the flowing velocity of increase, thus guarantee the flow identical with the catheters irrigation air feed F1 of the first constant pressure air feed.
Therefore, in the second constant pressure in pneumatic control, the liquid etc. adhering to the inside of constant pressure supply conduit 82 removed by the brief flushing air feed with high flowing velocity.
Fig. 6 shows the third constant pressure for pneumatic control method.
Fig. 6 is the third constant pressure of display for the time diagram of the catheters irrigation air feed in pneumatic control and constant pressure air feed.
In addition, in the third constant pressure in pneumatic control, constant pressure air feed C3 is performed with certain hour interval, catheters irrigation air feed F3 was performed before each constant pressure air feed C3, then pressure measxurement is performed, but in the example in figure 6, catheters irrigation air feed F3 and pressure measxurement are performed twice.
